Abstract

PURPOSE:To make it possible to wash the economizer automatically by a method wherein boiler water is sprayed automatically for a predetermined period of time after the operation of a blower is stopped by a timer. CONSTITUTION:When a combustion signal is integrated by a timer T1 for a predetermined time t1 and when the blower is not operated, a fluid control device is opened for a predetermined time t2 by another timer T2 and after a neutralizing washing liquid is sprayed on the economizer, the fluid control device is closed to thereby enable the economizer to be washed automatically.
